Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] Example 1:

[0028] like Figure 1-4As shown, the automotive bushing adhesive removal device provided by this utility model includes: a base plate 1, on which a fixing mechanism is provided, the fixing mechanism including a clamp 2 disposed above the base plate 1. In this embodiment, the clamp 2 is an internal expansion structure (other types of clamps can also be used). The clamp 2 can pass through the center of the circular automotive bushing from the inside, supporting and fixing the automotive bushing from the inside out. This structure is common in the machining industry and will not be described in detail here. A rotary motor 5 is installed at the bottom of the clamp 2. The housing of the rotary motor 5 is connected to the base plate 1. The rotary motor 5 is used to drive the clamp 2 to rotate. An edge trimming mechanism is also provided above the base plate 1. The edge trimming mechanism includes a chip removal groove 3, and an electric push rod 6 is installed at the bottom of the chip removal groove 3. The housing of the electric push rod 6 is connected to the base plate 1. The clamp 2 passes through the chip removal groove 3. A cutting edge assembly 4 is provided on one side of the chip removal groove 3. The cutting edge assembly 4 includes a fixed plate 7 installed on the chip removal groove 3. A cutter bar 8 is slidably installed on the fixed plate 7. One end of the cutter bar 8 passes through the fixed plate 7 and is equipped with a cutter head 9. The cutter head 9 is installed vertically and can cut off the rubber edge of the rotating circular automotive bushing. A rotating shaft 11 is rotatably installed on one side of the fixed plate 7. An elliptical cylindrical pressure plate 10 is installed on the rotating shaft 11. Connecting plates 12 are installed at both ends of the rotating shaft 11. A connecting rod 13 is installed between the connecting plate 12 and the base plate 1. One end of the connecting rod 13 is rotatably connected to the connecting plate 12, and the other end is connected to the base plate 1. In use, the circular automotive bushing is first fixed on the fixture 2. Then, the rotary motor 5 is started, driving the bushing on the fixture 2 to rotate. The electric push rod 6 is activated, causing the chip removal groove 3 to rise. This, in turn, pulls the connecting plate 12 via the connecting rod 13, causing it to drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the pressure plate 10 to rotate. The rotating pressure plate 10 presses the cutter bar 8 closer to the fixed plate 7, causing the cutter head 9 at the end of the cutter bar 8 to gradually approach the rubber edge of the bushing. As the bushing rotates, the cutter head 9 approaches the rubber edge and gradually cuts off the rubber edge. Then, the chip removal groove 3 is lowered to the initial height, the rotary motor 5 stops, the bushing is removed from the fixture 2, and a new bushing is installed. The rubber edge removal process for the next bushing can then begin.

[0029] By setting up a base plate 1, a fixing mechanism and a cutting mechanism, the chip removal groove 3 is raised by an electric push rod 6. At the same time, the chip removal groove 3 is raised by a connecting rod 13, a connecting plate 12, a rotating shaft 11 and a pressure plate 10, which can drive the cutter bar 8 to move the cutter head 9 close to the rotating circular automotive bushing, so as to conveniently remove the rubber edge on the automotive bushing.

[0030] Example 2:

[0031] like Figure 3As shown, a guide rod 14 is installed on the fixed plate 7, which passes through the tool holder 8. A return spring 15 is installed on the guide rod 14. During use, the tail of the tool holder 8 gradually approaches the fixed plate 7 under the pressure of the pressure plate 10, which compresses the return spring 15 until it is compressed to its limit (it cannot be compressed further). At this time, the tool holder 8 stops moving and descends in the chip removal groove 3. The compressed return spring 15 pushes the tool holder 8 to move in the opposite direction and reset, thereby limiting the lateral limit position of the tool head 9 and facilitating the reset of the tool holder 8 and the tool head 9. Similarly, the rotation angle of the pressure plate 10 can also be limited (the rotation angle of the pressure plate 10 is less than 90 degrees, preferably 60-70 degrees, to prevent the pressure plate 10 from rotating too much and failing to reset).

[0032] By installing a guide rod 14 on the fixed plate 7 and fitting a return spring 15 on the guide rod 14, the cutter head 9 can be easily limited and reset.

[0033] Example 3:

[0034] like Figure 1-4 As shown, an installation slot 16 is provided on the chip removal groove 3, and a bolt 21 is installed in the installation slot 16. The bolt 21 is threadedly connected to the fixing plate 7. When in use, the position of the fixing plate 7 in the chip removal groove 3 is adjusted, thereby adjusting the distance between the cutter head 9 and the clamp 2, which is convenient for adapting to the operation of bushings of different diameters. Then, the bolt 21 is tightened to fix the fixing plate 7 on the chip removal groove 3.

[0035] By opening an installation slot 16 on the chip removal groove 3 and installing a bolt 21 in the slot, the distance between the cutter head 9 and the clamp 2 can be easily adjusted, making it convenient to adapt to the operation of bushings of different diameters.

[0036] Example 4:

[0037] like Figure 4 As shown, a mounting hole 17 is provided on the chip removal groove 3, through which the clamp 2 passes. A chip removal hole 18 is also provided on the chip removal groove 3. Therefore, during use, the debris generated when removing the glue edge can be discharged from the chip removal hole 18.

[0038] By opening a chip discharge hole 18 on the chip discharge groove 3, it is possible to easily discharge chips from the chip discharge groove 3.

[0039] Example 5:

[0040] like Figure 2 As shown, a chip guide groove 20 is installed at the bottom of the chip discharge groove 3 (below the chip discharge hole 18). The chips discharged from the chip discharge hole 18 fall into the chip guide groove 20 and are guided to the outside by the guide groove 20, which facilitates the collection of chips and makes it easier to clean the equipment later.

[0041] By installing a chip guide groove 20 below the chip discharge hole 18, it is possible to collect debris conveniently, which facilitates subsequent equipment cleaning.

[0042] Example 6:

[0043] like Figure 1-2 As shown, a telescopic spring 19 is installed between the bottom end of the connecting rod 13 and the base plate 1. When in use, when the chip removal groove 3 is raised, the cutter head 9 performs the glue removal operation on the bushing. After the glue edge is removed, if the chip removal groove 3 continues to rise, the telescopic spring 19 will continue to be stretched. The chip removal groove 3 can easily lift the bushing on the clamp 2, so that it can be removed from the clamp 2 and the bushing can be easily removed.

[0044] By installing a telescopic spring 19 between the connecting rod 13 and the base plate 1, the bushing can be easily removed from the clamp 2, making it more convenient to use.

[0045] Working principle: In use, first, the circular automotive bushing is fixed on the fixture 2. Then, the rotary motor 5 is started, driving the bushing on the fixture 2 to rotate. The electric push rod 6 is started, driving the chip removal groove 3 to rise. Then, through the connecting rod 13, the connecting plate 12 is pulled, causing it to drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the pressure plate 10 to rotate. The rotating pressure plate 10 presses the cutter bar 8 closer to the fixed plate 7, thus causing the cutter head 9 at the end of the cutter bar 8 to gradually approach the rubber edge of the bushing. As the bushing rotates, the cutter head 9 approaches the rubber edge and gradually cuts off the rubber edge. Then, the chip removal groove 3 is lowered to the initial height, the rotary motor 5 stops, the bushing is removed from the fixture 2, and a new bushing is installed. The rubber edge removal operation of the next bushing can then begin.
